Answer:

4 meters

Step-by-step explanation:

Let the height at which the top of the ladder is be represented by h. The sketch of the question forms a right angled triangle. So that applying the Pythagoras rule,

/hyp/^{2} = /Adj 1/^{2} + /Adj 2/^{2}

5^{2} = h^{2} + 3^{2}

25 = h^{2} + 9

h^{2} = 25 - 9

   = 16

⇒ h = \sqrt{16}

      = 4

Therefore, the height at which the top of ladder is placed is 4 meters.

Answer: 10 units

Step-by-step explanation:

If the trail starts at R(-2, 4) and goes towards S(3, 4), the distance between the two points would be the sum of the absolute value of the x values. That means it's 2 + 3, which is 5. The distance between the 2 points is five. Doing the same thing with S(3, 4), and T(3, -1) but with the y values, you get 5. adding the 2 distances up you get:

5 + 5 = 10
